CHOP. The current standard chemotherapy regimen for NHL is CHOP.  CHOP stands is a combination of cyclophosphamide, doxorubicin hydrochloride (Adriamycin), vincristine (Oncovin), and prednisone. It is proving to be particularly effective for many stages of lymphoma when used in combination with rituximab, a monoclonal antibody. Some studies of this combination in low-grade lymphomas have reported response rates of 70 - 100%. CHOP alone is still preferred for HIV patients, who tend to have a toxic response to rituximab.

CVP. This stands for cyclophosphamide, vincristine, and prednisone. It may be used with CHOP in certain cases.

Fludarabine and Nucleoside Analogues. Fludarabine (Fludara) is a type of drug called a nucleoside analogue. It is one of the most active drugs for treating low-grade lymphomas and may be effective for other NHLs, including mantle cell lymphomas. Promising regimens containing fludarabine are under investigation. For example, FND (fludarabine, mitoxantrone, and dexamethasone) may be helpful in combination with rituximab for certain patients, including those with indolent NHL. Other nucleoside analogues include gemcitabine and cladribine. Toxicities and infection rates from high dose nucleoside analogues have been high. Fludarabine also has been associated with a risk for leukemia.

Bendamustine. This potent drug has shown to be effective for indolent NHLs and possibly aggressive lymphomas. One study suggested that a single dose of low-dose etoposide, taken by mouth, may be beneficial for elderly patients.

Side Effects and Complications

Side effects and complications of any chemotherapeutic regimen are common. They are more severe with higher doses. Side effects may increase over the course of treatment.

Common Side Effects. Common side effects include:

• Nausea and vomiting -- Drugs known as serotonin antagonists, such as ondansetron (Zofran) or granisteron (Kyril), can relieve these side effects in nearly all patients given moderate drugs and most patients who take more powerful drugs. In one study, nearly all patients who took a combination of dexamethasone (a steroid) in combination with ondansetron within 24 hours of chemotherapy experienced either a significant reduction or complete control of nausea and vomiting.
• Diarrhea
• Hair loss
• Weight loss
• Depression
